sMoKnLnss ORCHARD-HEATER.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed April 2, 1913. Serial No. 760,038.

To all whom it may concern Be it known that I, Summon: MoomnA, a subjectof the Emperor of Japan, residing at Upland, in the county of SanBernardino and State of California, have invented a new and usefulSmokeless Orchard-Heater, of which the following is a specification.

This invention relates to a heater especially designed for protectingorchards from frost, and the main object of the invention is to providea heater for this purpose which will burn a suitable fuel, such aspetroleum distillate, in an eflicient and economical manner without theproduction of smoke.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate the invention, and referringthereto: Figure 1 is a vertical section of the heater. Fig. 2 is asection on line aF-m" in Fig. 1. Fig. 3 is a horizontal section on linem -w' in Fig. 1.

The heater comprises atank or pot 1 which may be of any suitable form,but is preferably rectangular in horizontal cross section, and isprovided with upwardly flaring walls 2. A cover or top member 3 rests ontop of the tank 1 and is provided with downturned flanges 4: .forengaging with the upper edges of the tank 1 to retain the cover memberin position, said cover member being preferably provided with a handle 5to enable it to be removed from and put into position. Tank 1 isprovided with a series of holes or air inlets 7 in each of two sides ofsaid tank, and a closure member is provided for said holes consisting ofa slide 8, .guidedin guideways 9 on the side of the tank, said slidebeing provided with holes 7 adapted to re ister with'the holes 7 in theside of the tan A stack 10 is provided within the tank, the bottom ofsaid stack resting on the bottom of the tank and said stack extending upthrough the cover member 3 some distance above the top of the tank. Saidstack is provided with openings 12 at its lower edge for allowingpassage of oil or fuel and with several series of openings 13 atdifferent heights in the stack for passage of fuel and vapor, and withan upper series of openings vapor only. Said stac 10 is preferably ofsheet metal, the openings 13 being formed by stamping out the metal, themetal being left attached at the upper edges of said openings and beingbent inwardly to form 15 for passage of' deflectors or battle plates orprojections 14. Above the cover member 3 the stack 10 is provided with aseries of openings 16 for admission of air, this series of openings being regulated by a closure member 17 in the form of a sleeve adapted toslide frictionally on the stack 10 so as to be retained in any desiredposition thereon, the upper end of this sleeve being adapted to extendabove the top of the stack to form a continuation thereof.

The operation is as follows: Suitable fuel, such as petroleumdistillate, is placed in the tank 1, the stack 10 and cover 3 are put inposition and the fire is started by igniting gasolene or other readilycombustible material within the tank or within the stack. The slide 8 isopened sufliciently to allow air to pass into the tank in suflicientamount for partial combustion of the fuel and the resulting vapor passesinto the stack through the openings 13 and 15, being obstructed in itspassage upwardly into the stack by the deflector means 14, so as toinsure a more effective mixture of the vapor and incoming air andprevent flames from reaching directly' from the bottom of the stack tothe top thereof. To more effectively secure this battling action, theprojections or deflectors 14 are staggered or arranged in differentangular positions so that the upper series of deflectors extend abovethe spaces between the deflectors of the lower series. The vapor passingupwardly in the stack receives additional air through the air inletopenings 16 in the stack which are opened more or less, according torequirements by suitable adjustment of the regulating sleeve 17, theamount of air so supplied being regulated to produce a mixture of vaporand air which burns at the top of the stack in a substantially smokelessflame. If more air is required at any time, it can be procured byraising the regulating sleeve 17 and a greater or more efiectivegeneration of vapor may be secured by opening the slide 8 to a greaterextent so as to admit more air through the perforations 7 and 7 to theinterior of the tank constituting the generating chamber.

What I claim is:

1. A tank having a closed cover and pro vided with air inlet openings, astack resting on the bottom of the tank and extending upwardly throughsaid cover, said stack having openings at its bottom for passage of ingsfor passage of vapor, and deflectors ex- ..tending inwardly above saidlast named openings.

2. A tank having a closed cover and pro--.

vided with air inlet openings, a stack resting on the bottom of the tankand extending upwardly through said cover, said stack having openings atits bottom for passage of fuel, and openings above said bottom openingsfor passage of vapor, deflectors extending inwardly above said lastnamed openings, said stack being provided with perforations above thelevel of said cover and a regulating sleeve surrounding said 15 stackand frictionally engagingthe same to regulably close said perforations.o In testimony whereof, I have hereunto set my hand at Los Angeles,California this 2nd day of April 1913.
